LUBRICATING DEVICE.

b all whom i may concern:

, Be it known that I, AUGI'E L. HANSEN, a citizen of the United States, and a rsident of Evanston, in the county of Cook, State of Illinois, have invented certain newand useful Improvements in Lubricating Devices, of which the following is a specification.

My inven'tion'relates to lubricating devices and `particularly tov oil cups of the splash feed type. i

Among the important objects of my 1nvention are: to provide improved construction and arrangement for'readily permitting an oil bearing cup part to be applied to or removed from a nipple member which is permanently secured to conduct oil to the sur# faces to be lubricated; to provide improved and more efcient means for detachably se curing the cup and nipple members together; to provide improved arrangement for permitting the removed inverted cup member to be readily filled with oil, and improved means for preventing escape of the oil when the cup is returned to upright position; to provide improved construction and arrangement whereby when the cup is applied to the nipple member, pressure will be introduced into the cup'and a charge of oil forced therefrom to be delivered to the bearing surfaces, thus insuring immediate lubrication service to the bearings after they have been cleaned or first put into use; to provide improved and more efficient means for feeding and conducting Oil into the discharge passageway ofthe cup; to provide improved arrangement which permits adjustment to be readily made for speed of oil flow from the cup; and in general, toV

provide a simple, practical and efficient lubricating device of the class referred to.

On the accompanying drawings l show a lubricating device which embodies the above and other features of my invention. On these drawings, Y

Application filed September 29, 1919. Serial No. 327,197.

Fig l is a sectional view on plane 4-4, Fig. 3.

The nipple member of the device comprises the threaded plug section 5,'the polygonal wrenchyreceiving head 6 and the spindle 7 extendingupwar'dly from the head. The axial passageway 8 extends upwardly through the plug and head sections and a distance upwardly through the spindle `7, lateral passageways 9 through the spindle communicating with the vertical passageway 8. The section a above the lateral passageways 9 is of slightly less diameter than that of the base section?) of the spindle. The upper end c of the 'spindle is externally threaded and below this threaded end the diameter is reduced to form the frusto conical section Z between vthe threaded end and the section a'. In the top of the head 6 is the annular groove 10l in 'which a washer 11 of suitable material Vsuch as fiber is seated.

The cup is constructed of sheet metal and comprises the cylindrical body' part 12, the dome shaped top 13 integral therewith, and the bottom 111. This bottom has the outer flange 1,5 whichfwhen inserted snugly fits in the body part 12. 1t also has the inner annular upstanding flange 16 surrounding the centra-l opening' 16 which receives the lower end of the tube 18, the tube being secured at its lower end to the bottom by means of the flange 16 and extending upwardly centrally through the cup member into engagement at its upper end with the top 13 when the bottom 1e is inserted, the tube being secured to the bottom before the bottom is inserted into the cup body. The tube is of substantially Vuniform diameter both internally and externally and snugly fits the base b of the nipple member, it having the vent holes 17 which, when the cup member is applied to the nipple member, are just above the flange Y 16 to be in communication with the interior of the cup at certain times.

The upper end'of the tube is internally threaded to receive the threaded end 0 of the nipple member, such threaded connection drawing the base Vof the cup member against the washer 11 to effectra sealing fit. To insure'secure threaded engagement and to prevent self loosening of the cup member,

the upper end ofthe tube is preferably bifurcated and the two opposedl semi-circular sections e and f bent inwardly a distance securely held with sealing engagement on the nipple member. To facilitate turning of the cup member, it has the knurled belt 18. Surrounding the tube 18 and reciprocable thereon is the cylindrical sleeve 19. The sleeve is of such length that its upper end will bef'below the oil inlet openings 2O ofthe tube 18 when the cup is in upright position. These inlet openings 2O may be at any point at the upper end of the tube, but as shown, they are formed by enlarging the lower ends of the slots between the bifurcation ends c and f. The upper end of the sleeve 19 is of enlarged diameter to form the annular cup or pocket 21, and at opposite sides at this pocketthe sleeve is cut away to leave clearance or entrance passageways 22.

Describing now the operation, the nipple member is screwed into a supporting frame F to register its outlet passageway 8 with the duct 23 which leads to the bearing surfaces to be lubricated. ber, it is inverted and oil charged thereinto through thetube 18. When the cup is inverted, the sleeve 19 will be against the top 13 and the air vent openings 17 will be ex posed and will connect the interior of the cup with the exterior thereof. As the oil flows downwardly in the tube 18, it enters "thercup through the openings 20. 1f the passageways 22 of the sleeve are not opposite the openings 20, then the oil flows into and. through the pocket 21 until it reaches the passageways 22 from where it flows into ,the cup. During such inflow of oil, the disany oil therein and'this oil will flow down-V wardly through the annular space s between Y' the spindle and tube and through the passageways 9 and 8 into theY duct the bearing surfaces.Y

Thusv when acup is applied to a bearing surfacer which has not before been lubricated 2?) andv to or after a bearing surface has been cleaned,

the applicationof a filled cup will cause a chargeof oil to be delivered which will be ample toV coverthe lbearing surfaces.

To fill the cup memments of the cup cause the. oil to be flung.

upwardly and part of it enters the openings 20 which are adjacent the frusto conical section (Z of the spindle, the oil entering the enlarged space g and then gradually flowing down the capillary space s into the passageways 9 and then through the passageway 8 to the bearing surfaces. Some of the oil splashes from the cup intothe pocket 21 of the sleeve 19, or against the tube 18 at the passageways 22. This oil is lifted as the sleeve Y19 is reciprocated by the jolting and conducted to the openings 20, the sleeve acting somewhat like a pump plunger to raise the oil so thatit may flow through the open'- ings 20. The sleeve Vtherefore performs two functions, namely to close the air vents 17 when the cup is inupright position'and disconnected from the nipple structure, and to act as a plungerfor carrying oil to the outlet openings 20. Y

The speed of oil feed fromvtheicup is determined by the thickness of the capillary space s between the spindle and tube. The enlarged space g acts Vas a reservoir to receive oil fromv the openings 20 but the oil ows from the reservoir slowing down the capillary space to the Vpassageways 9. If it is desired to increase the speed of flow, then the diameter of the section a vof the spindle would be correspondingly increased to in-4 and therefore reduce the resistance to flow therethrough. At its' lower end kthe tube 18 snugly lits the base b of the spindle and oil cannot escape. In case any oil should succeedin working its way Ldownwardly at this point', the sealing engagementeof the cups bottoml with the washer 11 would prevent escape of the oil. The engagement of the tube 18 with the section b of the stem also closes the air vent holes 17 so that the sleeve 19 is relieved of this duty when the @up has been applied to the nipple member.

he device would of course operate more or less efficiently with the sleeve 19 omitted, but then the cup could not be set in upright position as the oil would escape, Y'

but would have to be applied immediately to the nipple, the section'b of the spindle closing the vent openings. However, the sleeve 19 permits the'cup to be set down in kupright position afterlilling thereof or at any other time without leakage, and the sleeve alsoA assists in'carrying oil to the out-v let openings 2O when the cup structure is reciprocated. '5

In some oiling devices, felt or other material has been interposed inthe path of the oil to retard its flow.` vSuch yretardation is not uniform and therefore unreliable. In my improved construction, the oil is being continually thrown in the reservoir or funnel space g at the upper end of the tube 18, but its flow from such reservoir to the nipple passageway is retarded by the. restricting or capiliary space 8. Such retardation is uniform and constant so that the feed of oil into the bearing surface is uniform.

In do not, of course, desire to be limited to the exact construction, arrangement and operation shown and described as changes could Yreadily be made without departing from the spirit and scope of the invention.V
